## Title

    Proposed fix: [Anthropic C# Anthropic.Mcp] 'MCP resource links must be resolved by the MCP client before conversion.' / 'MCP audio content is not supported by the Anthropic API.'

## Body

    Recommended action: Read linked resources via the MCP client (resources/read) and pass contents; drop or transcribe audio content; ensure MCP tools declare an object inputSchema.
    
    Option: Resolve or drop unsupported MCP content [evidence: documented_workaround]
    Steps:
    1. for resource_link: await mcp.ReadResourceAsync(uri) then convert
    2. filter AudioContentBlock
    Expected: Tool result converts
    
    Evidence basis (self-declared by the contributing chat client): untested.
